Strange-antistrange and charm-anticharm asymmetries of pion in 't Hooft model
Mingliang Zhu, Siwei Hu, Yu Jia +2
As a sequel of our preceding work [S. Hu et al., Phys. Rev. D 108 (2023) 9, 094040], we investigate the strange-antistrange and charm-anticharm asymmetries in the parton distributi…
Two-loop QCD corrections to Higgs radiative decay to vector quarkonium
Yu Jia, Zhewen Mo, Jia-Yue Zhang
The exclusive production of through Higgs boson radiative decay may serve a clean channel to extracting the charm quark Yukawa coupling. We calculate the two-loop QCD correct…
Light quark mass dependence of nucleon mass to two-loop order
Long-Bin Chen, Siwei Hu, Yu Jia +1
We investigate the nucleon self energy through the sixth chiral order in the covariant chiral perturbation theory (PT) in the single baryon sector. The validity of the e…
Exclusive production of double light neutral mesons at the colliders
Junliang Lu, Cai-Ping Jia, Yu Jia +1
In this work we investigate the exclusive production of a pair of light neutral mesons in annihilation, where the final state bears an even -parity. The production proc…
Hard-scattering approach to strongly hindered electric dipole transitions between heavy quarkonia
Cai-Ping Jia, Yu Jia, Junliang Lu +2
The conventional wisdom in dealing with electromagnetic transition between heavy quarkonia is the multipole expansion, when the emitted photon has a typical energy of order quarkon…
Light-cone and quasi generalized parton distributions in the 't Hooft model
Yu Jia, Zhewen Mo, Xiaonu Xiong +1
We present a comprehensive study of the light-cone generalized parton distribution (GPD) and quasi-GPD of a flavor-neutral meson in the 't Hooft model, {\it i.e.}, two-dimensional…
Heavy quark fragmentation function in 't Hooft Model
Yu Jia, Zhewen Mo, Xiaonu Xiong
We carry out a comprehensive study of the quark-to-meson fragmentation function in the 't Hooft model, i.e., the two-dimensional Quantum Chromodynamics (QCD) in lim…
Parton distribution of intrinsic charm in two dimensional QCD
Siwei Hu, Yu Jia, Zhewen Mo +2
We present a detailed investigation on the intrinsic charm content in a light meson within the 't Hooft model, namely, the two-dimensional QCD in large limit. The intrinsic c…
